Unless I am misreading Sigma's Corporation announcement of the two lenses, Pentax is left out on both models.

This could be bad news for the lens. I found this on Sigma Corporation announcement when they first announce the two lenses.
“The Global Vision Art, Sports and Contemporary lines were developed to help photographers identify lenses that are best suited to their specific photography and these two lenses are perfect examples of that intent,” Mark Amir-Hamzeh, president of Sigma Corporation of America. “While they share a focal length and many outstanding features, these lenses are designed with different photographers in mind. Both high-performance lenses, one is for the professional-grade action shooter; the other for photographers looking for high performance and portability.”
The 150-600mm F5-6.3 DG OS HSM Sports offers the highest level of performance and durability with a splash and dust proof construction, and features dimensions of 4.8 inches by 11.4 inches, with a weight of 100.9 ounces. It contains 24 lens elements in 16 groups – including two FLD and three SLD glass elements – with a minimum aperture of F/22 and minimum focusing distance of 102.4 inches. Its maximum magnification ratio is also 1:5. The Sports lens will be available in Sigma, Canon and Nikon mounts.
The 150-600mm F5-6.3 DG OS HSM Contemporary lens is the first hyper-telephoto zoom lens from the Global Vision Contemporary line, and will enable easy handling with a smaller build than its Sports counterpart. It is equipped with a splash and dust proof mount, and while the weight of the lens is still to be determined, its dimensions will be 4.1 inches by 10.2 inches. The lens will feature 20 elements in 14 groups – including one FLD and three SLD glass elements – with a minimum aperture of F/22 and minimum focusing distance of 110.2 inches. Its maximum magnification ratio is 1:5. It will be available in Sigma, Canon, Nikon and Sony mounts.

This is off of Sigma's website for both S & C models.
"Sigma will convert the current mount of your Sigma Global Vision lens to another of your choice. Sigma lenses currently from the Contemporary, Art or Sports line, in Sigma, Canon, Nikon, Sony, Pentax mounts can be converted to Sigma, Canon, Nikon, Sony or Pentax*. They cannot be converted to either an APS-C or a Full Frame format".
I don't know if this is meaning that both Sony & Pentax mounts are coming or not. or Can you buy a Canon or Nikon mount and have it converted to Pentax by Sigma?

Thank you. I had done a search, but come up empty. This is a positive note. I hope it will happen.

Hi all,
I have been reading everyones post and must say I am impressed with the setups of the Q for long range shooting. I have the K5 + DA* 300, but often find it not having the reach I need for my wildlife shooting. The new HD 560 lens was in my buying box until Pentax released the price...$7000 is a tall order. So I am now very much looking into a Q setup. However, I have a question to all... what is the largest print size of high quality (displaying on the wall) can one go with the Q? I would need to be able to print at least up to a 13 x 19 and match quality of print to my K5. Can this be done or is this outside the Q and its small sensor?
